High spatial resolution imaging of the star with a transiting planet WASP-33
Andy Moya, Herve Bouy, Franck Marchis +2
The recent discovery of a transiting planet around WASP-33, the misalignment of the stellar rotation axis and the planet orbit, the possible existence of an additional planet in th…
Spectroscopy of Very Low Mass Stars and Brown Dwarfs in the Lambda Orionis Star Forming Region. I. Enlarging the census down to the planetary mass domain in Collinder 69
A. Bayo, D. Barrado, J. Stauffer +7
Whilst there is a generally accepted evolutionary scheme for the formation of low-mass stars, the analogous processes when moving down in mass to the brown dwarfs regime are not ye…
Young Stellar Objects in NGC 6823
B. Riaz, E. L. Martin, R. Tata +3
NGC 6823 is a young open cluster that lies at a distance of ~2 kpc in the Vulpecula OB1 association. Previous studies using CCD photometry and spectroscopy have identified a Trapez…
Ruling out unresolved binaries in five transitional disks VLT/NACO: deep 2.12 and 1.75 μm narrow-band imaging
Silvia Vicente, Bruno Merın, Markus Hartung +8
Aims. We aim at detecting the presence of companions inside the inner hole/gap region of a sample of five well known transitional disks using spatially-resolved imaging in the near…
A spectral comparison of (379) Huenna and its satellite
Francesca DeMeo, Benoit Carry, Franck Marchis +7
We present near-infrared spectral measurements of Themis family asteroid (379) Huenna (D~98 km) and its 6 km satellite using SpeX on the NASA IRTF. The companion was farther than 1…
